NFG Games + GameSX

Namco's Cyber Lead cabinet is a weird sort of thing, with heaps of functionality. So much functionality that most owners will probably never use a lot of it. Like the LED display at the top of the cab, or the cabinet's link function for two player games. And all of these neat toys come with a new connector and pinout.

For the most part, all the connectors in the cabinet are one of two types, both made by AMP. The data communications are mostly EI series, and almost everything else is Universal Mate n Lock. Except the connectors on the power supply board, where there are two Molex Mini-Fit Jr.

Note: The Mini-Universal Mate-N-Lock connector can use either plug or socket connectors in both plug and cap housings. Pay close attention to which ones you need.

The JVS CONV board converts the cab's internal JVS communications to JAMMA for use with older boards. It is self contained, with a single JAMMA connector handling all player inputs, unless you need the 6th button, which requires the kick harness. It does a bunch of other things as well, like create an s-video output, lower the JAMMA spec video to VGA levels, manage stereo/mono sound, and so on.

It's called the N48 Harness according to Namco docs, so this is the N48 Harness Connector. It's labeled J104. It handles extra player buttons, as well as extra speaker outputs from the PCB.

Pin	Function	Pin	Function
1	Speaker +	6	P1 Button 5
2	Speaker -	7	P2 Button 5
3	GND	8	P1 Button 6
4	P1 Button 4	9	P2 Button 6
5	P2 Button 4	10	GND

This board is used twice in the Cyber Lead cab, once behind the control panel and again beneath the LED display at the top of the cabinet. The boards are identical but the connectors and components on them are different, so they're not interchangeable.

Pretty standard stuff here. Labeled J33 (P1) and J35, these are EI-series 12-pin connectors, used to connect all the signals from the control panel to the PCB. The pinout is the same for P1 and P2. The manual indicates a red connector is used for player 2.

Pin	Function	Pin	Function
1	Up	7	Button 2
2	Down	8	Button 3
3	Left	9	Button 4
4	Right	10	Button 5
5	Start	11	Button 6
6	Button 1	12	GND

Labeled J38 on the board, this connector is wired to the coin input and counter. Despite having wiring for 2 coin slots, the Cyber Lead only has one coin input.

Pin	Function	Pin	Function
1	GND	4	Counter 1
2	Coin 1	5	Counter 2
3	Coin 2	6	Service

+5V is available from J31, using a 2-pin connector.

Pin	Function	Pin	Function
1	+5V	2	GND

The key is sort of useless on a 2-pin connector so pay attention.

The connection to the LED panel itself, from the LED board beneath it, uses the same 10-pin connector as the N48 harness. It's a straight-through pinout, but if you want to know what the pins are:

Pin	Function	Pin	Function
1	S-DATAR	6	X-LATCH
2		7	SCAN-CLK
3	S-CLK	8	YG
4	LED-ON	9	S-DATAG
5	LED-ENB	10

The 6-pin mini-DIN plugs on the two boards are standard PC/Mac serial ports. You can buy a standard cable and plonk it in, or DIY for some reason.

It's a straight through configuration, except pins 2 and 3 (TX/RX) are swapped.

While the manual indicates the default controller is a Seimitsu LS-56, the schematic (And many peoples' experience) suggests the actual stick was a somewhat rare LS-33 (or LS-33NA) with a pinout that doesn't match Seimitsu's normal connector.

The connector used for Sanwa and Seimitsu sticks is a JST NH-series 5-pin. The pinout for the LS-33 and the normal Seimitsu/Sanwa mechs are:

The specific order for the Seimitsu and Sanwa sticks is fiendishly complicated because it's wholly dependent on orientation. If you mount your stick with the connector facing down, the only pin you can rely on is ground, the rest will change based on that orientation. As a result, I can't claim this is totally accurate, though I believe it is. There's a decent chance the Sanwa and Seimitsu pinouts are in reverse order, but since the connector can simply be flipped, it hardly matters.

The Namco pinout is correct, based on a connector on the RIGHT side, if you're looking from the top of the control panel. If you're looking at it from below, it'll be on the left side (P1 stick connector towards center of panel, P2 towards edge).

There are two output connectors on the PSU, which are 8 and 6 pin Molex New Mini-Fit Jr connectors.

Note: The 2.5V is not used. It's not known if the PSU actually puts out this Voltage.

This plug connects the power cables from the PSU to the rest of the cabinet. The PSU itself has two plugs, which connect to this one, and from there to the rest of the cabinet.
